Dupple writes: InterDigital Inc. (IDCC) won an appeals court ruling reviving its effort to force Nokia Oyj (NOK) to pay patent royalties on the third generation of mobile-phone technology. InterDigital rose to the highest since April.

The U.S. Court of Appeals for the Federal Circuit today overturned a U.S. International Trade Commission decision that cleared Nokia (NOK1V) of claims it infringed InterDigital patents, and sent the case back to the agency for further review. The ruling was posted on the court’s website.

The commission “erred in construing certain critical claim terms in both patents,” the appeals court said. The patents in the case, first filed in 2007, cover power control and high- speed data transmission, InterDigital contends.Link to Original Source
